Green-Beckham, a wide receiver from Hillcrest High in Springfield, Mo., made his decision Wednesday on National Signing Day.

He had been one of the biggest mysteries of the recruiting season, with Arkansas, Oklahoma and Texas being the other schools that looked like they had a chance.

“It is an honor to say that I will be continuing my education at Missouri,” Green-Beckham told a live TV audience.

It was thought he was heading to Arkansas until this past weekend, when an official visit to Missouri set off a flurry of rumors that he committed to the Tigers.

He described his abilities.

“To make big plays, you have to go up and work the hardest you can be and create a whole lot for your teammates,” Green-Beckham told Sporting News in December. “I could take the pressure of double-teams, because I knew somebody else would be open on the other side … I knew the double-teams were coming but I knew each play that I need to go all out.”
